Hot on the heels of the unveiling of Facebook Graph search came Wonder, from Russia’s search engine giant Yandex. This is the voice-controlled search app for iPhone that, as Sarah Silbert reported, “pulls data from your Facebook, Foursquare, Instagram and Twitter accounts to answer questions like “What music do my friends listen to?” Essentially, it’s a mobile version of Facebook’s new Graph Search.”

This striking similarities did not go unnoticed by the the latter company, which promptly blocked Yandex from accessing it’s data. The two are now in talks, but it’s clear Facebook has the upper hand here.
